openCamera（）が終了した直後にAndroidがopenGallery（）を呼び出した直後

Question

openCamera（）が終了した直後にopenGallery（）を呼び出すにはどうすればよいですか？私はカメラを使って写真を撮りたい、ギャラリーに保存して（私ができる）、そしてすぐに撮影した写真を選択するためのギャラリーを表示する。 openCamera（）が呼び出しを終了すると、openGallery（）は決して表示されません。私がopenCamera(); openGallery();と書いても動作しません。 openCamera（）をスキップし、代わりにopenGallery（）を呼び出します。私を助けてください。

コール即ちonActivityResult

@Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     Log.i("request", requestCode + " result " + resultCode + " intent " 
       + data); 
     super.onActivityResult(requestCode, resultCode, data); 
     if(requestCode == RESULT_SAVE_ITEM){ 
      clearItemContents(); 
     } 
     else if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) 
     { openGallery(); 
     } 
//...rest code
